Part Number: TPS62811-Q1

Hi team,

Could you advise if EN pin of TPS6281x-Q1 have hysteresis to avoid unstable startup at slow ramp rate?

I plan to connect EN pin to VIN pin and the supply for VIN/EN pin start up very slow.

I would like to know if EN pin can startup normal in this configuration.

regards.

Hello Tsuji-san,

The EN pin has a hysteresis of 100mV (nominal). If you have concern on the ramp voltage on EN pin voltage, you can place an RC network across VIN and EN pins (refer to the ckt. below).
